The diverter is movably positionable within the body such that the diverter can assume a first position, second position and third position. The body includes one or more exhaust ports, a supply port, a first outlet port and a second outlet port. The body and diverter are configured such that: when the diverter is in the first position, the supply port and first outlet port fluidly communicate and the one or snore exhaust ports and second outlet port are fluidly isolated; when the diverter is in the second position, the first outlet port and one of the one or more exhaust ports fluidly communicate and the supply port and second outlet port are fluidly isolated; and When the diverter is in the third position, the first outlet port and second outlet port fluidly communicate and the supply port and the one or more exhaust ports are fluidly isolated.
